Is it too early to POAS?

Okay, so stopped breast feeding DS in November as wanted to TTC number 2 and hadn't had a period since getting pregnant (DS was 12 months old). Got my first period on 10 Jan. DTD lots and got my second period on 6 Feb. Based on last month AF is due today but I can't honestly remember what my normal cycle is like as I've been pregnant or BFing for nearly two years. Don't want to get my hopes up so is it too early to POAS?
